IMPROVEMENT lN BARBED FENCE-WIRES.

Specification forming part of Letters Patent No. 168,550, dated October11,1875; application filed August 20, 1875.

CASE B.

To all whom it may concern:

Be it known that we, FRANK ARMSTRONG and GEORGE DOOLITTLE, ofBridgeport, county of Fairlield and State of Connecticut, have inventedan Improved Barbed Gable Fence- Wire; and we do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making part of thisspecification, in which- Figure 1 is a side elevation of a portion of afence formed of our improved cable fence-wire. Fig. 2 is a' face view ofone of the barbs, showing a section of two wires binding the barb.

The nature of our invention consists in a combination of barbs made ofpieces of sheet or plate metal, pointed and notched on their edges aboutmidway of the points, and two strands of wire twisted spirally upon oneanother, and upon the outer edges of the barbs,

in such a manner that each of the strands of wire enters a notch of thebarbs.

This construction obviates the necessity of perforating the barbs, andinsures their being firmly held at two points by the cable fencewire,and also prevents them turning independently of said wire.

The fence-wire itself is also very strong, and can be cheaply andexpeditiously made.

In the accompanying drawings, A A are posts of a. wire fence; B B,staples or eyes for confining the wires to the posts; 0, the fence-wirecable; and D D, the barbs.

The wire cable is formed of two strands, a a, twisted spirally upon oneanother, and the barbs are made of sheet or plate metal by cutting outpieces resembling a lozenge, and then notching the edges midway betweenthe points b b of the lozenge-pieces, as indicated at c 0. These barbsare placed at proper distances apart, and the wire strands a c of thecable twisted around them in the mann er shown in Fig. l of thedrawings.

The pointed barbs may be painted white or coated with white metal.

It might be practicable to have a single strand of wire extend from postto post and use short sections of wire in connection therewith, the longwire and short sections being twisted together and around the barb; butthe two continuous wire strands, as shown, are the most durable and farpreferable to the proposed modification.

What we claim is v The barbed fence-wire cable formed of two strands ofwire, and having sheet or plate metal barbs with two points and notchededges confined between them, with their flat sides in the samelongitudinal plane, or nearly so, with the cable, the wires being woundspirally upon the barbs by passing them on the outside and into thenotches between the points of the barbs, substantially as and forthepurpose described.
